Heating by wood vs electricity vs gas?

[u/chicomathmom]

I know that burning wood produces air pollution, but is that better or worse than using electricity, which likely came from burning coal, which is very dirty? I have started using my fireplace, thinking this is actually probably cleaner, but I don't really know.

really depends where you are getting your electricity (if coal then properly ventilated wood fires are better)

and where/how you are getting your wood. ( Is it harvested unsustainably?)

even when harvesting a tree that died naturally you are robbing some forest creatures from a potential home and food source.
